The great news is that the door is plumb, level, and square. The "If I could have done it over" news is that there is a threshold step-up of nearly an inch on the hallway side, and a 3/4" lip on the interior side.
The decision in my mind was to install the new flooring under the door, thus alleviating any issues with the flooring joining the pre-hung steel, 90-minute fire-rated Jeld-Wen six-panel door. I also did not know exactly what we were going to do with the floor in the hallway, now or in the future renovation of the first floor down the road.
So, here are the images and the results.
|Removing the packing blocks|
|Nelson checking for level.|
|Conference time--shimming procedure.|
|Hinge side needs the jack-stud installed.|
|With the jack-stud installed with some additional strip shims.|
|Shimmed latch side on the king-stud edge to bring it flush with the door's casement.|
|Door ready for slip in brackets to hold it to the framing.|
|Fire-rating on door.|
|Also rating the door-jam.|
|Door mat--placed down to help mask the interior threshold "lip so people will not trip..."|
|Door swings easily and not on its own. It also closes completely. Seems to be installed within rated tolerances. Now to choose a lock-set.|
